Inclusions in steel can cause serious issues such as clogging of the submerged entry nozzle (SEN) during continuous casting and defects in finished products. Controlling inclusions during steelmaking is therefore vital. While traditional microscopy offers detailed inclusion data, it is time-consuming in terms of sample preparation and analysis. Optical Emission Spectroscopy (OES) provides a faster alternative, enabling quicker analysis that can be used for real-time process control in secondary metallurgy.
At Ovako's steel plant in Smedjebacken, this master thesis offers you the chance to apply OES inclusion analysis to optimize CaSi addition for selected steel grades - a key step towards cleaner steel and improved castability.
A thesis for those eager to combine materials science with process optimization
Inclusions strongly affect steel quality and casting performance. By harnessing OES inclusion analysis, you will help improve our understanding of how CaSi additions influence inclusion characteristics across different steel grades. This will enhance control over secondary metallurgy parameters and vacuum processing, reducing defects and improving product reliability.
Working closely with Ovako's experienced steelworks team, you will analyze inclusion data from OES and contribute to developing optimized CaSi addition strategies tailored to various steel grades.
The outcome? Enhanced knowledge and practical recommendations that directly support better steel cleanliness and casting efficiency at Ovako.
Why choose Ovako?
